Hand-held Monitor User’s Guide – June 1994
Monitoring a Genius Block
Select F2 (Monitor Block) from the Analyze menu to:
Display the I/O type of all circuits on the active
block.
Display (not change) forces on the active block.
Display the bus presently selected by the BSM
Controller.
Making the Block Active
If the block is not presently selected as the “active”
block, follow the steps below.
1. From the Analyze menu, select F3 (Block/Bus
Status).
2. Press F1 (Next) or F2 (Previous), to reach the
device’s description screen.
3. When the block’s screen appears, press F3 (Ac-
tive) to make it the active device. (On a dual
bus, the HHM must be on the same bus as the
active block. If it is not, either move the HHM
or force the bus selection)
4. Press D MENU to return to the Analyze menu.
After selecting the active device, use F1 (Monitor
Block) to monitor its data. This is a example
display for a discrete I/O block:
R E F S (block references)
OI
BSOIOIIOIOIOII
A1O11OO1
3456789O
Monitor Block screens for other types of Genius
blocks are described below.
Block References
On all the Monitor Block screens for a Genius
blocks, line 1 shows the block references. If *
symbols appear instead, the references are out of
range for the CPU host currently setup for the
Hand-held Monitor. For example, if a block is
assigned to Series Six registers, and the HHM is set
up for a Series 90 host, the HHM displays
*symbols instead of references.
If the HHM is set up for PCIM mode, references
are not used; a device description appears instead.
Monitor Block Display for Discrete I/ O
and Input Blocks
For a discrete block, the Monitor Block display
shows the I/O type and current state of each
circuit. This is an example display for an 8-circuit
grouped I/O block:
R E F S (block references)
OI
BSOIOIIOIOIOII
A1O11OO1
3456789O
Line 1 indicates the block’s I/O type:
I= Input
O= Output
OI= Combination (I/O)
Line 2 shows the last digit of each circuit’s
reference address. The abbreviation on line 3
describes the I/O type of each circuit:
I= Input
IT= Tri–State input
O= Output
OI= Output with feedback
Bs = Circuit that controls a BSM
Line 4 shows the current state of each circuit. This
information is updated continuously as the I/O
states change.
An underline means a circuit is forced (and does
not reflect actual circuit status):
O= OFF
O= forced OFF
1=ON
1
= forced ON
If the circuit is configured as a BSM controller, the
selected bus is displayed on line 4. If forced, the
active bus letter is underscored.
A= bus A
A= forced to bus A
B= bus B
B= forced to bus B
Displaying Additional Circuits for a 32-circuit DC
block: Press a key from F1 to F4 to toggle the
display between circuits 1 to 16 and circuits 17 to 32.
